The Design And Research Of Moving Target Auto-Tracking System Based On DSP

With the fast development of the society, the development of Target Tracking System is more and more mature. Target Tracking System, which plays an important role in the society, is widely used in various fields of military, industrial and commercial. The suggestion of intellectualization further accelerates the development of Target Monitor System. The Moving Target Auto-Tracking has become one of the most popular topics of monitoring field. What is more important, its appearance realized the transform from the passive tracking pattern to active tracking pattern. And Moving Target Auto-Tracking can become an intellectualized tracking via calculation and forecasting of Moving Target.The theory of moving target identifying and tracking is discussed in the first section. The methods of target detection are analyzed in sequence image which include moving target, and the calculation methods of mass center are introduced. Then, the template of moving target is abstracted out, which is applied in moving target matching and tracking.In the next section of this dissertation, the design and implementation of Moving Target Auto-Tracking monitor based on TMS320DM642 is studied. After analyzing the performance and characteristics of TMS320DM642, the implementation scheme of Moving Target Auto-Tracking monitor with TMS320DM642 as the core processor is put forward. The hardware of the system includes such function blocks as video decoder A/D, video encoder D/A, data buffer, DSP, CPLD, UART, data memory and FLASH. This dissertation introduces the hardware of every function block and the realization of system timing. According to the practical measurement of this system, the performance of both hardware and software all meet with such requirements as stability, reliability and real time etc. This project has successfully completed, and all its technical specifications are aligning with the requirements.
